Veronica is cooking dinner. She puts a pot roast in the oven, and sets the timer for one hour. She checks on the pot roast several times over the hour, but only finds that it is done after the timer goes off, then and only then can she eat. This is an example of a ____________ schedule of reinforcement: 1) Fixed ratio 2) Fixed interval 3) Variable interval 4) Variable ratio

Fixed interval

This type of schedule produces a high rate of responding, typically accompanied by postreinforcement pauses. 1) fixed interval 2) fixed ratio 3) variable ratio 4) variable interval

fixed ratio

Variable interval (VI) schedule: 1) Amount of time required to elapse before a response will be reinforced varies from trial to trial. 2) The number of responses required for reinforcement varies from one reinforcer delivery to the next. 3) Individual has to perform a fixed number of responses for the delivery of each reinforcer 4) A fixed amount of time has to pass before a response can be reinforced

Lowe and colleagues (1983) explained their observation that humans generated either high or low rates of responding, but not the typical schedule patterns observed in animals, during schedule training, by arguing that: language causes humans to behave according to a rule rather than the arranged contingencies schedule studies in humans are too short to develop the stereotypical patterns schedule effects do not generalize from animal to human behavior humans are not motivated to be in the study so they do not pay sufficient attention to the contingencies

language causes humans to behave according to a rule rather than the arranged contingencies

When considering ratio and interval schedules of reinforcement: interval schedules produce a higher rate of response ratio schedules produce a higher rate of response to get the highest rate of responding the researcher must alternate between ratio and interval schedules rate of responding is equal

ratio schedules produce a higher rate of response

Variable ratio schedules with high mean ratios (e.g., VR 100) have fewer short ratios following one another and are likely to result in longer PRPs shorter PRPs the absence of any PRP the highest response rates

shorter PRPs

The critical measure on progressive-ratio (PR) schedules is typically: the rate of responding the frequency of responding the length of the postreinforcement pause the breakpoint where the organism fails to complete the schedule requirement

the breakpoint where the organism fails to complete the schedule requirement

This schedule generally produces a high rate of response with little or no postreinforcement pause. 1) fixed ratio 2) fixed interval 3) variable ratio 4) variable interval

variable ratio

Fixed interval (FI) schedule: 1) The number of responses required for reinforcement varies from one reinforcer delivery to the next. 2) Amount of time required to elapse between reinforcer availability varies from trial to trial. 3) Individual has to perform a fixed number of responses for the delivery of each reinforcer 4) A fixed amount of time has to pass before a response can be reinforced

What is the relationship between an analysis of behavior perspective and the organism's memories and thought processes? It is important to use behavior as a means to infer both cognitions and memories in the individual exhibiting the behavior An analysis of behavior perspective discourages speculations and inferences about memory and thought processes Without an understanding of the organism's thought processes, behavior cannot be changed An experimental analysis of behavior rejects free choice and therefore sees cognition and memory as irrelevant
